I have roamed fanfiction.net for 4 months. During my time, I found many good and bad fanfiction. Here are the list of obscure fanfic that made me spent a whole night reading them.
Undying Gensokyo by WillieG.R.
A gory action adventure horror story featuring Aya and Satori as they battled many monstrous version of Gensokyo resident.
A Satori's Tale by Antimatter.
On the behalf of the Enma, Satori venture to the surface to solve the current incident. It wasn't an easy task for the satori simply because:
1. Nearly half of the people on the surface hates her.
2. Reimu was trapped in the Netherworld.
3. She had to deal with upcoming demon invasion.
4. There's a poisonous doll looking for revenge.
*hopes enthusiastically that one of my FF.net stories get mentioned by someone*
Here's something extra for ya.
